digital marine radar scanning like never before.

Get Powerful Performance
GMR 18 is a 4 kilowatt radar with 36 nm range. At 18 inches in diameter,
it is twice as powerful as most other radars in its size and price range.
Combine that with the antenna’s 5.2° beamwidth, and you’re looking at
the best weather penetration and target definition in its class.

To help you avoid traffic on the water, the
GMR 18 provides MARPA target tracking, which allows you to track the
bearing, course, speed and predicted closest approach of up to 10 targets.
And like all Garmin radars, GMR 18 has self-contained signal processing,
which provides you with a more precise, easy to read signature.

Connect to the Garmin Marine NetworkThe GMR 18 transmits data over the
Garmin Marine Network, a 100-megabit plug-and-play proprietary network
that gives you the ability to expand your boat’s system as needed. Once
connected to the network, you can use any network-compatible Garmin
chartplotter as your radar screen. And as an aid to locational awareness,
you can overlay the GMR 18 radar image on the chartplotter's map page. You
can also split the on-screen display so that you can view the map and the
standard radar page simultaneously.
